Terminal leaves window corner remnants on my desktop

[soustruh]

Windows Terminal version

1.21.3231.0

Windows build number

10.0.26100.2894

Other Software

No response

Steps to reproduce

• I work with Windows Terminal for several hours, create many tabs, sometimes close them. I mix PowerShell and WSL shells, but I don't think there's any connection with the type of shell.
• I use Win + D a lot, I also rearrange windows (Win + ←/→) quite often, then maximizing them up again (Win + ↑).

Expected Behavior

Everything should be rendered correctly.

Actual Behavior

There are artifacts left over on my desktop:

• When VSCode is minimized, I see a horizontal row of window corners in the bottom left corner of my screen.
• When it is displayed, those corners are drawn on top of each other in the upper left corner of my screen.
• Right now I noticed there is a Rendering section in Terminal Settings, I tried switching rendering mode from Auto to Direct 2D and Direct 3D. Doing so immediately helped me get rid of the row of corners in minimized state, but the top left corners in displayed state are still there. I think the corners that disappeared will eventually come back anyway. I will modify this ticket when it confirms.

This looks it might be the same problem as #15219. We've actually had a number of similar reports over the years, and at least some of them were found to be triggered by MicaForEveryone, so if you're using that - or any kind of UI tweaking software - it may be worth disabling it temporarily to see if it makes any difference.

Thanks for your reply! However, I don't use anything to tweak standard Windows UI. 🤷‍♂️

As I wrote previously, switching rendering mode made the corners disappear for a while, but they're back already. I can't find what made them reappear though.
